## Description

This project is a cross-platform implementation of the WebRTC standard, providing a comprehensive library for building real-time audio, video, and data communication applications. It functions as a peer-to-peer networking framework and media processing engine, enabling direct, low-latency connections between devices without relying on central servers. By strictly adhering to official protocol specifications, the library ensures interoperability with browsers and other native communication software across mobile, desktop, and server environments.

The engine distinguishes itself through a modular, interceptor-based media pipeline that allows for custom logic injection during transmission, alongside advanced network traversal capabilities that navigate restrictive firewalls and NAT configurations. It provides robust connection resilience through automated session renegotiation and supports complex transmission strategies, including simulcast and packet-level congestion control, to maintain stream quality across varying network conditions. Security is integrated through encrypted transport protocols and handshake obfuscation techniques designed to protect user privacy and bypass network analysis.

Beyond core connectivity, the project offers a broad suite of tools for media handling, including error correction, packet retransmission, and audio encoding. It supports efficient resource management through port consolidation and data channel interleaving, while providing diagnostic observability for monitoring connection health and performance. The codebase is designed for multi-environment deployment, compiling into native executables to ensure consistent behavior across diverse hardware and operating systems.
